New water-soluble imidazolium-based and benzenetriol-based ligands and their 3:2 ligand-to-lanthanide sandwich-type complexes, [Ln2(L1)3H2O], [Ln2(L2)3H2O], and [Ln2(L3)3H2O] (Ln = Er(III), Gd(III), and Lu(III)), were isolated. Upon 980 nm excitation, the Er(III) complexes exhibited metal-centered up-conversion emission in the solid state and in aqueous solution. When incubated in HeLa cells, the complexes appear to localize in the mitochondria, and red and green Er(III)-centered up-conversion emission was observed.

Salophen ligands and their complexes with transition metals Cu(II), Fe(II), Fe(III), and Co(II) were synthesized and characterized by UV–vis, IR, and 1H NMR spectroscopy. The catalytic activity of the...

Uranium is most stable when it is exposed to oxygen or water in its +6 oxidation state as the uranyl (UO22+) ion. This ion is subsequently particularly stable and very resistant to functionalization d...
